Let's assume you have supplement angle
Now when you talk about multiplication you can simply say...
And that will give you the answer.
Answer:
-1
Step-by-step explanation:
first 5+3=8
8-9=-1
To find out if they are parallel we need to see if the gradient is the same, to do this we need to get y in terms of x:
assuming the first equation is x+y+7=0
y=-x-7
and
y=x-3
The gradient is the coefficient of x (the number infront of x)
For equation 1 the gradient is -1, and for number 2 it is 1, therefore they are not parallel.
However to check if they are perpendicular we need to see if their gradients multiply to equal -1.
-1*1=-1 therefore they are perpendicular
Answer:
it is definitely negative, i think it is -3/2
Step-by-step explanation:
is there a better picture of the graph?
A graph can show that a rate of change is constant as long as the graph is of a straight line.
Any curvature in the line suggests a rate of change that is variable, but otherwise it is constant.
